Fabrication of an Atom Chip for Rydberg Atom-Metal Surface Interaction Studies
(University of Waterloo, 2007-09-28)This thesis outlines the fabrication of two atom chips for the study of interactions between ⁸⁷Rb Rydberg atoms and a Au surface. Atom chips yield tightly confined, cold samples of an atomic species by generating magnetic ... -
Bidirectional mapping between self-consistent field theory and molecular dynamics
(AIP Publishing, 2007-10-08)A bidirectional mapping scheme that bridges particle-based and field-based descriptions for polymers is presented. Initial application is made to immiscible homopolymer blends. The forward mapping (upscaling) approach ... -
Particle Distributions in a Block Copolymer Nanocomposite
(American Chemical Society, 2008)Self-consistent-field theory is used to predict the center-of-mass distribution of spherical nanoparticles embedded in the lamellar phase of a diblock copolymer melt. The calculation is performed in the dilute limit, where ... -
Intense laser field ionization of atom and molecular ion
(University of Waterloo, 2008-01-24)In order to understand how does the intense laser interact with matter we first of all study the ionization process. In this highly nonlinear region the conventional perturbation theory will fail to predict the experimental ... -
On Magic State Distillation using Nuclear Magnetic Resonance
(University of Waterloo, 2008-01-25)Physical implementations of quantum computers will inevitably be subject to errors. However, provided that the error rate is below some threshold, it is theoretically possible to build fault tolerant quantum computers that ... -
Physical Properties of Shear Oriented Cocoa Butter
(University of Waterloo, 2008-01-25)Cocoa butter is a highly complex system of triacyglycerides which has been shown to crystallize in a markedly different fashion under the application of shear. A rheometer insert was developed to enable the intact extraction ... -
Impact of Geometric Uncertainties on Dose Calculations for Intensity Modulated Radiation Therapy of Prostate Cancer
(University of Waterloo, 2008-01-29)IMRT uses non-uniform beam intensities within a radiation field to provide patient-specific dose shaping, resulting in a dose distribution that conforms tightly to the planning target volume (PTV). Unavoidable geometric ... -
On the Classification of the R-separable webs for the Laplace equation in E^3
(University of Waterloo, 2008-04-29)In the first two Chapters I outline the theory and background of separation of variables as an ansatz for solving fundamental partial differential equations (pdes) in Mathematical Physics. Two fundamental approaches will ... -
Interaction of Nanosecond and Femtosecond Laser Pulses with Carbon: Deposition of Carbon Films having Novel Compositions
(University of Waterloo, 2008-05-22)A comparison of the composition and structure of carbon films deposited by ns and fs laser ablation of graphite is the subject of this thesis. In addition, the effect of irradiation on the surface of graphite has been ... -
Nanoparticle-regulated phase behavior of ordered block copolymers
(RSC publishing, 2008-06-30)Although block copolymer motifs have received considerable attention as supramolecular templates for inorganic nanoparticles, experimental observations of a nanostructured diblock copolymer containing inorganic ... -
Suppression and characterization of decoherence in practical quantum information processing devices
(University of Waterloo, 2008-08-01)This dissertation addresses the issue of noise in quantum information processing devices. It is common knowledge that quantum states are particularly fragile to the effects of noise. In order to perform scalable quantum ... -
Interplay of Disorder and Transverse-Field Induced Quantum Fluctuations in the LiHo_xY_{1-x}F_4 Ising Magnetic Material
(University of Waterloo, 2008-08-25)The LiHo_xY_{1-x}F_4 magnetic material in a transverse magnetic field B_x perpendicular to the Ising spin direction has long been used to study tunable quantum phase transitions in pure and random disordered systems. We ... -
Black Hole Thermodynamics and the Tunnelling Method for Particle Emission
(University of Waterloo, 2008-08-29)The semi-classical black hole tunnelling method is a useful technique to calculate black hole temperature and understand black hole thermodynamics. I will investigate the black hole tunnelling method in detail. I will ... -
Laser-initiated Coulomb explosion imaging of small molecules
(University of Waterloo, 2008-09-02)Momentum vectors of fragment ions produced by the Coulomb explosion of CO2z+ (z = 3 - 6) and CS2z+ (z = 3 - 13) in an intense laser field (~50 fs, 1 x 1015 W/cm2) are determined by the triple coincidence imaging technique. ... -
Femtosecond Time-Resolved Studies on the Reaction Pathways for the Generation of Reactive Oxygen Species in Photodynamic Therapy by Indocyanine Green
(University of Waterloo, 2008-09-12)Photodynamic therapy (PDT), which utilizes the combination of light and a photosensitizing drug to cause tissue damages, has emerged as a novel clinical approach for the treatment of numerous cancers, as well as some other ... -
Error characterization and quantum control benchmarking in liquid state NMR using quantum information processing techniques
